norn-UNTWISTING APPARATUS.

' Application filed November 23, 192.1.` Serial No. 517,387.

To all whom #may concern: y

Be it known that I, PETER BUND JAGGER, a subject of the King of Great Britain, residing at London, England, have invented `certain new and useful Improvements in and Relating to Rope-Untwisting Apparatus, of which the following yis a specication. f

rl `his invention relatesto improvements in mechanism for mechanically untwisting and reeling or spooling the separate strands of a rope or the separate wiresor groups of wires of a strand. In myl prior United States Patent 1,448,543 there is set forth mechanism for carrying out the above operation, the mechanism comprising spools or bobbins or drums mounted so as'to revolve ona common axis, while simultaneously rotatingindependently on their own axes, a gripping device for' gripping the rope or the like at a point situate on the produced common axis aforesaid, this gripping device` revolvingl on the common axis inthe same direction as thei spools 0r bobbins, and at a speed, relatively to the spools or bobbins to ensure untwisting.

According to the present invention the drive of rotation of each spool or drum round its own axis is effected by independent driving means capable of being operated to reel its appertaining Wire or strand-at a rate of speed which may be varied independently'of a given orbital speed of the spool so as to accommodate any particular rate of delivery from they strand*4 or rope being untwisted.v

Independent driving means operating intermittently. serve well.

`Thus under thepresent invention therotatory movement of each spool ofa number of spools, or each group of a'number. of series of 'spools is controlled Aand regulated according to conditions in working and independently of a given orbitalspeed of the spools, this conducing to a more efficient running of the spoolsl or bobbinsfor take up and ensuring an increased efficiency in the general working of the machine; the setting for the reeling of the strand or wire in accordance V'with any given lspeed of the machine Vand hence in proportion to the amount of unwinding taking place at that speed being easy. The rotatory movement of any'spool or any series of spools can be cut Y" down or lengtliened or stopped without affecting the .rotary movement of any' other spool or series of spools. Further under the present invention a group selection of certain of the spoolsv may be made for reeling corresponding .to the number of separate strands orseparate wires, or groups of wires, to be untwisted and reeled in a particular vjob, theidle spools then simply revolving about the common axis without having a rotatory movement imparted thereto.4

As a drive for aspool or drum meansof the go and return character serves well.

'Anexample of sucha drive is constituted by a cam component or its v,equivalent car-v ried for example on the framework of thev the vrevolution of the spool, on a movable slide or link component, to thereby impart tothe spool a partial movement of rotation in a direction suited t'o the reeling thereon of the wire, etc., the slide or llink component being under bias to return ,to normal position as soon as the'operative period ends.

' The coupling between thev slide orlink com- 7o .machina and operative, during'a period of sovl A modiliedform of drive forthe. drumsy `is also set out in thev following description.

The accompanying drawings illustrate a form of machine under the vpresent invention. f Figs. land 2 are respectively. side elevax.

`tion and plan views ofthe spool side'of the machine having a pawl and ratchet wheel drive for the spool and drum. Figs. 3 and 4 are respectively side elevation and part plan of the gripping or supply side ofthe machine showing a drive for the gripping rolls. Fig. 5 is an elevation of the cam disc and Fig. 6 an enlarged' view of the pawl and ratchet wheel drive. 'l

Referring to Figs. l, Zand 5. and 6 of the drawings a constructional .form of drive under the present invention as applied to the form "of machine set out inmy prio-r Patent No. 1,448,543- comprises a cam l mounted on a disc or plate 2 attached to the framework of the machine. Each spool or drum 3 is mounted on its otvn spindle 4 in a carrier 5 Which is connected tothe revolving drum or annulus 6 and revolves therewith. To accommodate the Working of the machine to the tension or drag of the rope or the like each carriery 5 is mounted so as to freely rotate about its longitudinal axis. Each spool 2 has a partial rotatory movement intermittently imparted thereto in the desired direction about its spindle a by means of a ratchet Wheel 7 fixed on the spool and a one-Way acting ratchet pavvl or click 8 cooperating therewith. Movement is imparted to this pavvl by a lever and link feed device 9 slidably carried bythe carrier previously referred to Slots. 5? allovv for. the back and forth movement of the. feed device in the carrier. nonfre'turn detent 10 is provided for the ratchet. Wheel. The endof the feed. device remote from the ratchet paWl or click is so fashioned as by a projecting offsety or spindle4 11 as to contact with a cam 1 or a number thereof during each revolution about the common axis7 and at such contact the ratchet pawl operates the ratchet Wheel on the spool, thereby giving a partial rotatory movement to the spool and reeling a portion of the. strand or Wire on to the spool. Ther feed. device is under spring control 12 for effecting a return to normal position upon breaking contact With the cam.

The cam ,1 is arranged adjustable by means of a pivotal mounting and an adjusting screw 13 controlled by ay hand Wheel 14. Thus the setting of the cam can be effected to regulate the extent of the partial rotation of the spool, or to WithdranT the cam entirely from the path of movement of the offset or spindle.

The lay out of the cams is dependent on the positioning of the carriers on the revolving drum. Thus one cam may suffice for a number of spools when theseA are mounted so as to travel in the same orbital path.

In Figs. 1 and 2 are shown suitable means 16 for distributing the windings on the spool. 17 is a suitable form of confining device and 18 is a suitable form of conducting device for the separate Wires or groups of` Wire of a strand. 17 is driven by 18 thro-ugh the medium of the bevelivheels 18a and 17a. 19, 19a is the drive for the drum or annulus 6.

Referring, to Figs. t and 5', the gripping rolls 2O are mounted in adjustable bearings 21. The rolls 2O are under the control of a drive of the reciprocating character Whereby the feed of theA Wire is effected. This drive is indicatedv by an adjustable cam component 21 and slide or link component 22, 22iL under bias to return to normal position. The slide or link component 22, 22a^has one Way acting ratchet pavvls or clicks 23 cooperating with ratchets 211 on the gripping rolls 20. 25 is the supply roll and 26.J 27 the drive for this side ofthe machine.

Tn the particular machine shown the Wire is taken from the supply roll 25 through the hollow driving shaft 27 to the gripping rolls 20. After leaving the gripping rolls each strand is passed to its respective confining device 17,. conducting device 18, distributor 16 and spool 3.

The main core is` led through the hollow driving shaft 19L to the end of the machine.
